T0 whom it may concern:

Be it known that I, CHARLES DRATZ, a subject of the King of Belgium,residing at Brussels, in the Kingdom of Belgium, have invented a certainnew and useful Process of and Apparatus'for Printing MulticoloredDesigns, of which the following isa specification.

The present invention relates to improvements in printing multicolordesigns on textiles by means of solid coloring-matters imprinted onwetted warp-threads of a tissue in course of weaving. In thisprocess ofprinting the design to be printed is represented by a series of blocksof juxtaposed colors, and this design in the known process is applied tothe warp-threads in their passage from the warp-beam to the fabric beingwoven. This necessarily brings about the mutual contact of neighboringwarp-threads, so that it is impossible to prevent the diffusion of thecoloring-matters from one thread to the next and to obtainclearly-defined color outlines. The present improvements do away withthese drawbacks. These improvements consist principally in holding apartor spacing on the warp-beam all warp-threads which are destined to formpart in the composition of atissue, so that they occupy a greater widththan they should occupy in the weaving. In this manner the contactbetween two wetted neighboring threads is absolutely prevented. Then Iimpregnate simultaneously these threads so separated with thecoloring-matter, and I do not let the warp-threads fall back to thewidth intended for the tissue be fore this coloring-matter has entirelydried in the fibers. Then there is no more danger of difiusion of colorfrom one thread to the others. I

My improvements further consist in assembling the warp-threads soprinted in groups so as so make of them warp-threadgroups to beafterward combined by the weft-yarn or filling in the weaving in such amanner as to produce thick tissues printed throughout their thicknessand showing the printed design on both sides.

Finally my improvements concern the means for printing on thewarp-threads so kept apart on the warp-beam so as to obtain the regularimprint of an outline design on these threads, to effect the drying ofthe printed threads, and to prevent any malformation of the design whenthe width of the warp-thread tissue is reduced in the weaving.

The accompanying drawings show as a mat-.

ter of illustration the application of my improvements in printingtissues in course of weaving and the mechanical means for the practicalworking of same.

In the drawings the figures represent the following details.

Figure 1 is a view in vertical section of a loom for the execution of myinvention. Figs. 2 and 2 are diagrams of this loom, showing the designto be printed and the manner in which the design is made in the weaving.Fig. 3 is a view in detail. Fig. tlS aview in detail showing separatelythe construction of the printing-roller. Fig. 5 is a separate viewshowing the manner of assembling in groups the warp-threads for makingvery thick warpstrands. Fig. 6 is a view in detail showing the meansemployed for allowing the printing of extensive designs.

'In order to impregnate the straight threads with their color and toprevent the diffusion of the different colors toward places which theyare not intendedto touch, I spread the warp-threads upon the warp-beam Aby making them occupy a width greater than that which they will occupyat the place and at the moment of weaving. A receiver R, fixed on theframing of the l00m,contains the liquid intended to wet the stuff to bedyed. The latter is obliged to traverse this liquid by passing under aroller-guide B, plunginginto the receiver R. A fixed bar (J serves as aguide for the wetted threads leaving the receiver B. This bar 0 assistsa comb D to maintain and to direct the threads before their passage inproximity to the printing-cylinder E. This cylinder E constitutes theonly roller necessary for the printing of any design upon thewarp-threads of the fabric. This printingroller E, which is driven byany convenient means, is constituted, preferably, by a cylinder of woodor metal, upon which slides a sleeve carrying the design to be printedmade up of a great number of small blocks of solid coloring-matterconveniently arranged in order to realize a composition in a manneranalogous to type setting. A printing-lever G,

E in order to effect thus the incorporation of the coloring-matter withthe wetted threads.

Immediately next to the roller E and the lever G is arranged a table H,heated by any means and intended to dry the threads as soon as they areimpregnated with coloring stuff by their passage upon theprinting-roller E and under the action of the lever G. The

threads so printed and dried must then be tightened together, so as notto occupy more 5 space at the lathe K than the width of the;

finished tissue shall have. To this end they pass between the teeth of acomb D, on which they occupy the same width as on the warpbeam A, andbetween the teeth of the combs p p, on which they occupy only the widthof the tissue; but as the gradual concentration or narrowing of thethreads between the teeth D and p 19 would of necessity produce inthreads of the same length an uneven run, and consequently amalformation of the de-v sign, I arrange bet-ween the comb D and atension-roller B an arched comb P, (shown separately in Fig. 3,) betweenthe teeth of which pass the straight threads of the warp in such amanner that the threads from theE middle of the warp-bea-mfor instance,b'yi means of their passing over the highest part of the curvedcomb-make a course equal to: that of the exterior threads passing uponthe 5 lowest parts of the comb, Fig.3.

derstood that this arrangement, serving to? maintain an identicaltension of the threads upon the whole length of the warp-beam A,

will prevent the inequalities hereinbefore specified.

roller B, assures the regular advancing of the threads and themaintaining of their relative distances up to their arrival at thehealds 1) i p of the loom. My invention also comprises the'constitutionof eac'hwarpthread by the connection or combination of a certain nu mberof the threads from the warp-beam. The healds p p unite, as-illustratedin Fig. 4, these thread-sin more or less numerous groups in order toconstitute by means-of each group a warp formed by the juxtaposition ofa certain number of threads and which operates like a single warp, whichallows of obtaining.

a thick fabric upon which the printing and the different contours ofeach colored motive separately before the real operation of the weaving,which is then effected, as usually,

bymeans'of the usual organs of looms of this kind.

The printing-roller E can carry the complete design to be printed if thelatter :is not of a repeat requiring a very great length of fabric. Inthe contrary case, inorder to avoid the use of rollers of excessivediameter, it is convenient to use a second roller E and an endlesscloth, (see Fig. 6, for instance,) upon which are glued or fixed by anymeans the blocks of coloring-matter circulating in this case upon thetwo rollers E E.

The small blocks of coloring-matter can be formed in any appropriatemanner. For instance, they can be obtained by melting the color and thematerials necessary for its fixing upon the textile fiber and by addingany thickening and a certain qnantityof dextrin, gluten, or of any otherkind. In the paste so formed is introduced felt cut in tablets, and itis left there until it is completely impregnated with the coloringstuff. Then each tablet of felt is hardened and sawed in small cubes ofequal dimensions. These small cubes are then distributed, according totheir color and shade, in drawers, whence they are taken according tonecessity for compos ing the printing design. The latter can then servefor the impression of a relatively large quantityof textile stuff. Asmay be seen from the example hereinbefore described, my new process isespecially appropriate for printing visible design-s upon the two sidesof very thick fabric, this result being obtained by means of thepossibility of impregnating threads of thewarp arranged side by side andthen connected in real warp-chain formed by the juxtaposition of a largenumber of threads. It can be applied more 'easily in case of printingupon finished fabrics.

Having now particularly described and as certai-ned the nature of thisinvention andi-n what manner the same is to be performed, I declare thatwhat Iclaim is 1. The herein-described processof printing designs inmultiple colors upon textiles with The comb D, completed by thetensionsolid eoloring-matter on the juxtaposed and dampened warp-threadsof a tissue during the course of weaving consisting in spreading thewarp-threads upon a warp-beam, making them occupy at first a widthgreater than that which they will occupy at the place and at the momentof weaving in dampening and printing said threads in said-spread stateand then narrowing the width of the warp-thread to the width of thetissue to be formed, all substantially as set forth and for the purposespecified.

2. The hereindescribed process of printing designs in multiple colorsupon textiles with solid coloring-matter on the juxtaposed and dampenedwarp-threads of a tissue in course of weaving, consisting in spreadingthe warpthreads upon a warp-beam, mak'ingthem occupy a width greaterthan that which they will occupy at the place and at the moment ofweaving, then narrowing the width of the warp-threads to the width ofthe tissue, connecting the threads into groups or strands constitutingeach a thread or Warp-strand and finally effecting the crossing of saidgroups of threads with the Weft.
